We present a measurement of the pion form factor based on e+ e- annihilation data from the CMD-2 detector in the energy range 0.6 < sqrt(s) < 1.0  GeV with a systematic uncertainty of 0.8%. A data sample is five times larger than that used in our previous measurement. © 2007 Elsevier B.V. All rights reserved.
